You might start the deprogramming process since it’s obvious your son has been brainwashed by a well-oiled (pun intended) right-wing noise machine. Here are two generic questions you can always challenge him with, in a respectful manner:
1. What do you mean by [insert right-wing sneer word de jure, such as “woke”
2. Why should I believe what you are saying about it? (That is, what evidence do you have for this claim, and how reliable are your sources?)
Another possible question might be “what are the potential implications of taking the actions you propose to address this issue?”
